中文摘要：

根据牛顿环的光强公式，设计牛顿环的干涉仿真实验算法。利用VisualC＋＋6．0开发了仿真软件。给出原始法和近似法的两种计算方法，并给出两种方法干涉图样和光强的比较，比较的结果说明近似法可以代替原始法。近似法能分析干涉图样的性质。仿真结果的图样细致逼真，使整个物理过程变得直观形象，为光学的理论分析和实验教学提供了新的有效的辅助手段。

英文摘要：

According to the light intensity formula of Newton ring, the interference simulation algorithm of Newton ring is designed. The simulation software is developed by using VisualC ＋＋ 6.0. Two kinds of calculation methods of the original method and approximate method are given.The comparisons of interference patterns and light intensity of the two methods are presented, the results show that the original method can be replaced by the approximate method. The approximate method can analyze the nature of the interference pattern. The pattern of simulation result is delicate and distinct, which makes the whole physical process visual and provides a new effective supplementary means for optical theory analysis and experiment teaching.
